The “hula hoop” scanner

Abstract

In medicine, sports, bodybuilding, dressmaking etc, it is necessary to reliably measure human body. The device here presented can estimate without physical contact the perimeter of human body parts as waist, thigh, biceps etc. It can also measure the circumference of objects like tree trunks. The device actually scans the shape of the object's cross section and the perimeter measure is a byproduct. We think that the shape of human body provides much more information than simple perimeter measure, and may have many applications.
